Anew and useful Improvements in Lawn- Sprinlners, of which Vthe following is a specitiiaition.

This invention relates to what I shall for convenience term a lawn sprinkler, the object of the invention being to provide an article of this character which is susceptible of inexpensive manufacture and which has means of ineffective nature for uniformly distriluiting water or other liquid over a, definite or described area in a gentle manner. v

In the drawings accompanying and forming part of the present specification I have shown in detailone convenient form of einbodiment of the invention which will be set forthv fully in the following description. I do not restrict myself, however, to this particular disclosure; I may depart therefrom in several respects within the scope of the invention deiined by the claim following said description.

Referring to said drawings:

Figure l is a side elevation of a lawn sprinkler involving the invention.

Fig. 2 is a rear elevation of the same.

Fig. 3 is a horizontal section on the line 3 3 of Fig. l.

Fig. 4 is a top plan View, and

Fig. 5 a vertical section.

Like characters refer to like parts throughout the several views.

The article constituting the subject matter of the present case is capable of general use, although itis of particular advantage when used for sprinkling a lawn, being in tended to direct a body of water or it might be any any other suitable liquid suchfor instance as a germicide over a prescribed area; for instance half a circle. lhen used as a lawn sprinkler, the device is equipped with means for holdingit in a fixed position. This means may be of any suitable character, for instance a penetrating element which depends from the body or casing of the sprinkler head and which is thrust into the lawn or it may be anything of a similar character. When the sprinkler is mounted, and when it is supplied with the necessary liquid, this liquid is directed onto the lawn Vor other surface.

lV ith the foregoing general observations I shall now more particularly refer Lto what is illustrated.4 The device includes in its construction a casing or boxing as 2 which as shown is of practically cylindrical form. Although this shape isa goed one the casing, which constitutes the head of the article, may be of any other suitable shape. rThepositioning element is denoted by 3, and it may as shown consist of an ordinary nail driven through a perforation or opening in the bottoni of the casing or head 2, the wall of the hole or opening tightly embracing the shank of the nail just below its head in the manner shown in Letters Iatent 90452530, granted jointly to J. I-I. Atkins and myself on November 17, 1908. later or other liquid can be supplied to the casing or head 2in any desirable way, for instance by the nipple 4 adapted for connection with a hose or other suitable source of liquid supply; as represented the nipple is interiorly threaded to provide for the union therewith of a hose or other connection. The liquid whether water or something else is discharged from the casing or head 2 in seme suitable manner as through the perforations or needle openings 5 which may as shown be formed in the top of the casing or head 2, it being understood that when the supply of liquid ison this liquid is discharged from the head in a multiplicity of jets.

The jets of liquid issuing from these spray or needle openings 5 are positively directed by what I term a spreader such as 6. This spreader is semi-circular in cross section, being in the form of a shell or iange rising from the top of the head 2 in an angular manner `extending in an upward forward direction from its point of juncture with the said top. In fact the spreader may be described as consisting of a half inverted frusto-conical shell. In some cases it might be a solid but being in the form of a shell is a preferable construction, owing to the fact that it is an inexpensive one, more so in fact than where it is made solid. The reduced base of this spreader is of a less diameter than that of the casing or head 2. The needle openings 5 are in front of and adjacent to the base of the spreader. lVhen liquid in fine streams issues from these perforations or orifices 5, it strikes the spreader and is diverted in a forward direction in the form of a comparatively line spray or mist.

In the construction shown the spreader is ica shown provided at its ends with similar wings 7. These wings are in alineinent transversely of the sprinkler and extend outwardly from the spreader diametrically of the head 2. These wings or flanges extending outwardly beyond the head, their outer or side edges converging downwardly and their upper edges diverging downwardly. These wings or flanges prevent eiiectually the flow of the water or other liquid backwardly, the consequences being that a given area will be sprinkled. In the present instance this area is practically a half circle. Its radius may be varied in accordance with the size of the needle openings 5 or the pressure of the water. In fact it is not essential that I spray this particular' area. rlhe snrace covered, however, is practically half a circle. rlhe wings or lianges 7 which l have,V alluded to prevent as set forth the rear *ard How of the water, the consequence being that the area back of the sprinkler is left dry o1' comparatively so, certainly dry with .respect to the liront, so that one can reach the sprinkler without 'lear of the feet becoming wet, when it becomes necessary to change the position of the device. The sprinkler can also be held in the hand, and

the wings or flanges act as guards to prevent the user from becoming wet while manipulating the sprinkler.

I deein it desirable to call attention to the fact that some of the water or other liquid issuing from the openings or perfo rations 5 is deflected against the wings 7 and is directed by them laterally.
